Time Machine

Time Machine: what this Yggdrasil slot offers

Time Machine is a steampunk Victorian-themed video slot from Yggdrasil built around the studio's Pay-Rise mechanic, which expands the reels with every win and can unlock up to 16,807 ways to win by the time the grid reaches full size.

Theme and gameplay feel

The visuals lean into a retro-futuristic vision of Victorian England, filled with intricate brass machinery, glowing gears, and steam-powered devices rendered in fine period detail. The game starts on a 5x3 grid offering 243 ways to win, with matching symbols forming combinations from left to right across active paylines. Every winning spin triggers a respin and adds an extra row to the reels, gradually increasing the total ways to win as the grid grows. Once the reels reach their full 5x7 size, that expansion triggers the Free Spins round outright.

What the RTP means for you

Time Machine runs on a 95.5% RTP, a figure that sits close to the typical market average, giving players a fairly standard long-run return relative to the wider slots category.

Volatility and feature behaviour

This is a medium-volatility release, and the Pay-Rise structure rewards patience during the base game, since each consecutive win pushes the grid a little closer to its maximum size and the guaranteed Free Spins trigger. Once inside the bonus, players are awarded 7 free spins on the fully expanded grid, with +1 symbols landing on reels 1 and 5 awarding additional spins to extend the round further.

Max win potential and stakes

The maximum win sits at 5,000x the stake, a solid figure for a medium-volatility title, particularly given that the entire Free Spins round plays out with the maximum 16,807 ways to win already locked in. Stakes run from 0.2 up to 100 per spin, giving good flexibility for different bankroll sizes.

Verdict

The Pay-Rise mechanic gives Time Machine a genuinely satisfying sense of progression, with every base-game win nudging the grid toward its fully expanded state and a guaranteed shot at Free Spins. Combined with the polished steampunk presentation, it's a well-paced medium-volatility pick. Worth spinning the free demo at johnessyslots to watch the grid grow before playing for real money.
